foot-and-mouth dis·ease (FMD),
a highly infectious disease of worldwide distribution and great economic importance, occurring in cattle, swine, sheep, goats, and all wild and domestic cloven-hoofed animals caused by a picornavirus (genus Aphthovirus) and characterized by vesicular eruptions in the mouth, tongue, hoofs, and udder; humans are rarely affected.
An acute, highly contagious degenerative viral disease of cattle and other cloven-hoofed animals, characterized by fever and the eruption of vesicles around the mouth and hooves. It is usually not fatal. Also called hoof-and-mouth disease.
an acute extremely contagious rhabdovirus, specifically vesicular stomatitis virus, infection, primarily of cloven-hooved animals. It is characterized by the development of ulcers on the skin around the mouth, on the mucous membrane in the mouth, and on the udders. Horses are immune. The virus is transmitted to humans by direct contact with infected animals or their secretions or with contaminated milk, although this is rare. It should not be confused with hand-foot-and-mouth disease, which is caused by a different virus (coxsackie A). Symptoms and signs in humans include headache, fever, malaise, and vesicles on the tongue, oral mucous membranes, hands, and feet. Generalized pruritus and painful ulcerations may occur; however, the temperature soon falls, the lesions subside in about a week, and total healing without scars is complete by 2 or 3 weeks. Treatment is symptomatic. Also called aphthous fever. See also picornavirus.
foot-and-mouth dis·ease(fut mowth di-zēz)
Highly infectious disease of worldwide distribution and great economic importance, occurring in cattle, swine, sheep, goats, and all wild and domestic cloven-hoofed animals caused by a picornavirus and characterized by vesicular eruptions in the mouth, tongue, hoofs, and udder; humans are rarely affected.
an extremely contagious, acute disease of all cloven-footed animal species. It is caused by members of the genus Aphthovirus in the family Picornaviridae which has seven serotypes and at least 80 subserotypes. Clinically there is a syndrome of fever and vesicular lesions in the mouth and around the coronets. The first sign is often lameness. Spread is very rapid and the virus is very resistant so that the infection is readily transmitted on inanimate objects. The virus can also be transmitted over several miles by wind-borne carriage of aerosol infection from respiratory excretion of the virus. It is not fatal except occasionally in calves and young piglets, where it also produces a myocarditis, but herd productivity is reduced disastrously. A disease notifiable to the OIE (see Table 24). Controlled with a slaughter eradication policy in most countries, but the outbreak in the United Kingdom in 2001 indicates that this policy has limited public support. Called also FMD, aftosa.
foot-and-mouth disease m. d. virus (FMDV)
a picornavirus, seven serotypes, at least 80 subtypes, affecting all ruminants, pigs, hedgehogs and elephants. The virus is extremely acid-labile but survives well in offal, particularly glandular tissue and bone marrow which were commonly fed as garbage to pigs resulting in outbreaks of disease.
